electronegativity is the tendency of an atom to attract a bonding pair of electrons, therefore fluorine is more able to attract electrons then lithium (has a greater pull).
Electronegative charge increases across the periodic table to the right and up into the corner ( excepting the Nobel gasses ), so the two elements that would have higher electronegativity in that direction and in order. Oxygen and fluorine.
Even though Fluorine has the highest electronegativity among all the elements and it should have the highest electron gain enthalpy among all the halogens but this is an exception and chlorine has higher electron gain enthalpy than Fluorine. The reason for this is that the size of Fluorine atom is very small and hence there is very high inter-electronic repulsion among the electrons of fluorine. This makes incoming of another electron not very favourable. Even though fluorine has large negative electron gain enthalpy but for chlorine its even more negative.
Yes, Mg is more electronegative than Ca. By the Pauling scale Mg has an electronegativity value of 1.31 while Ca has 1.00. The higher the value, the more electronegative the element is. The electronegativity of the elements generally decrease down group II (the alkaline earth metals).
Lithium is significantly larger.
Fluorine is a neutral atom, though fluoride is an anion. Fluorine does not form cations, or any compound, complex ion, or coordinate complex in which it has a positive oxidation state, unlike the other halogens.
Fluorine has the highest electronegativity among the three elements. Oxygen is the second most electronegative, while chlorine has a slightly lower electronegativity compared to both fluorine and oxygen.
There are two elements. They are Fluorine and Oxygen
A fluorine atom has a higher electronegativity than an atom of any other element.
Yes, fluorine is more electronegative than hydrogen : it has the highest elemental electronegativity by the Allen method, at 4.193 to hydrogen's 2.300 (only neon is higher than fluorine, but it cannot be calculated using Pauling units because it forms no ordinary compounds).
Electronegative charge increases across the periodic table to the right and up into the corner ( excepting the Nobel gasses ), so the two elements that would have higher electronegativity in that direction and in order. Oxygen and fluorine.
The bond between hydrogen and fluorine is not a covalent bond. When hydrogen bonds with oxygen, nitrogen, or fluorine, then it is called a hydrogen bond. Hydrogen bonds will be stronger than a regular covalent bond, so the electronegativity difference will be higher.
Yes with any element with a higher electronegativity. Carbon has an electronegativity of 2.55 on the Pauling scale. Checkout the table in wikipedia in the article "electronegativity", you can see that nitrogen, oxygen , sulfur, and fluorine, chlorine, bromine, iodine all have higher electronegativities.
It is a small difference between the electronegativity of lithium (o,98) and sodium (0,93) - for Li the value is higher.
As I originally stated in my original answer, the bonds in a molecule of OF2 are covalent. The electronegativity difference between them, according to the Pauling values is 0.54, which indicates a slightly polar covalent bond, in which Fluorine has the higher electronegativity value.
Nonmetals tend to have a higher electronegativity value than metals. Fluorine, a nonmetal, has the highest electronegativity value.
All acids consist of some non-metallic element or radical that is combined with hydrogen. There is a quantity called electronegativity which measures the degree to which a given atom or radical attracts electrons. The higher the electronegativity that any given atom or radical has, the stronger the acid it will form when it combines with hydrogen. The highest known electronegativity is 4, which is the electronegativity of fluorine. Therefore, hydrofluoric acid is the stongest acid.
Hypo fluorite O-F is not possible because the electronegativity of fluorine is higher than oxygen and oxygen with fluorine should be positive , if oxygen is positive then hydrogen or any other positive ion can not attached to oxygen so hypfluorite is not possible.
